Global air travel and War contribution to emergence and reemergence of Diseases

1.Global air travel Global travel involves many people from diverse places across the world assembling at the enclosed terminal of the airports hence increase individuals probability of contracting or spreading a new disease or previously eliminated disease. Besides, Air travel involves many human contacts processed such as verification of passport, security screening etc. hence increases the possibility of spread or contracting of new disease. The cabin of a plane is airtight environment hence augment the possibility of contraction and spread of new or eliminated disease in case an individual on board is infected.

2. War warfare destroys necessary health public infrastructures and disrupts public service delivery such as immunization thus increases the possibility of re-emergence of the previously eliminated disease. Bio warfare (use of biological agents: bacteria, virus etc,) can contribute to the emergence and re-emergence of diseases (Example: Smallpox).
